Batch Image Background Remover

A Python CLI tool that processes multiple images from a directory, removes their backgrounds, and saves the results to an output directory.

Requirements

The tool should accept two command-line arguments:

1. Input directory path containing images to process
2. Output directory path where processed images will be saved

The tool must:

• Process all image files in the input directory (recursively including subdirectories)
• Remove the background from each image
• Save each processed image to the output directory with the same filename
• Show progress during batch processing
• Handle common image formats (PNG, JPG, JPEG)

API

def process_batch(input_dir: str, output_dir: str) -> None:
    """
    Process all images in input_dir by removing backgrounds and saving to output_dir.

    Args:
        input_dir: Path to directory containing input images
        output_dir: Path to directory where processed images will be saved
    """
    pass

if __name__ == "__main__":
    # CLI entry point that accepts input_dir and output_dir as arguments
    pass

Test Cases

• When given an input directory with 3 PNG images, it processes all 3 images and saves them to the output directory with backgrounds removed @test
• When the output directory does not exist, it creates the output directory before saving processed images @test
• When given an empty input directory, it completes without errors and produces no output files @test
